WAD stands for "Where is All the Data". IWADs are the base data files that came with each official id game. PWADs, or Patch WADs, are add-ons that can override the IWAD, for e.g., with new levels.

  • Infinity - The Doom Wiki at DoomWiki.org
  • A Fistful of Doom - The Doom Wiki at DoomWiki.org

    • For some reason always had it confused with the Inferno levels (specifically Crossing Acheron, which is the one good WAD I remember playing from that period)
    • Definitely remember things like the title screen graphic, the first map with the shotgunners standing around a pentagram, the random secret sectors.
